CodeIgniter global variable

I ran into a similar problem earlier today. I found that an easier way, rather than globals, was to use constants. You can define a constants file that will load from your index.php file:

// Include additional constants
$defines_file = 'includes/defines.php';
if (file_exists($defines_file))
{
    require_once($defines_file);
} 

Then you can add your constants to the defines.php file:

define(MY_CONSTANT,'my constant info');

This way they will be available in any file throughout the system either directly: echo MY_CONSTANT; or you can assign them to variables.

I decided this way would be easier for me as I would only have 1 location to go to when/if I needed to change the constants.
